Civility which creates a clean memory (consciousness) is key to happiness and good health; no matter the other person's perception.
I would look up the tmk on the county website:
http://www.hawaiipropertytax.com/Account...nu=PSearch&submnu=Account&cookieCheck=1
If you don't know what their TMK is, type in yours, then click on the map; it'll give you the surrounding TMK's.
Then, contact the person and ask them if you can have it removed. Then, place an ad, here or on craigslist "Free building materials, you disassemble." You'd be surprised about what others' consider valuable. One mans junk.......
If they give you permission to have it removed and no one replies to the ad, I can get some people together to help you remove it sometime.
This actually happened last year here; Names changed:
Henry and Lehua on road 26 built their temp house practically on the road. A.O. called the county to report it because they jog by it everyday and couldn't stand it. County sent Dept of Health Inspector Luis. Henry knows Luis. Luis told Henry it was A.O. Lehua not happy, Henry need Lehua happy. Very bad for A.O.
